albassman; Locate the fuel injection pump on your motor. Remove the drain screw on the lower end of the pump body and drain some gas from it into a glass jar. about 4 to 6 oz will do. look and see if there is any water in the bottom of the jar. If you see water, put some startron, or sta bil, in your tanks and try her again on the water. This usually takes care of mine when that happens to me……………..Mike
